A magnitude 4.2 earthquake hit 17 miles east-southeast of Julian at 5:39 p.m. on Sunday, causing weak-to-moderate shaking in San Diego County, the US Geological Survey says. The quake occurred on or near the Elsinore fault, which produced a 4.1 quake on October 2.

"This was a garden variety quake that happened on one of California's well-known faults," said Tom Rockwell, a seismologist at San Diego State University. "This happened in an area where moderate quakes are known to occur."

In fact, Sunday's shaker broke beneath Whale Peak, just north of an area that the USGS once called Earthquake Valley. The area was renamed Shelter Valley. The site also is near Agua Caliente hot springs.

Rockwell said that Sunday's quake appears to be a unique event that was not related to the Oct. 2 event, nor was it an aftershock of the 7.2 shaker that hit on Easter Sunday in April 2010. The quake broke in a desert area, but sent much of its energy through granite, causing it to be felt widely.

Early reports say the quake was most strongly felt in Escondido, Ramona, Julian, Borrego Springs, Carlsbad, El Cajon and Lakeside. The energy from a quake does not always fan out in a uniform way.
